With Christmas less than three weeks away, it's time for a holiday cheer check.

Are you already in the holiday spirit or could you use a boost? It just so happens there's a Naughty Santa Pub Crawl for that. Or a touring version of "A Charlie Brown Christmas." Even a chance to cycle with Santa.

Here's a sampling of some of the Green Bay area's more festive events:

Naughty Santa Pub Crawl

The word “naughty” got your attention, right? Wannabe Santas are encouraged to put on the red suit and beard — or dress up as one of his naughty or nice helpers — for a Saturday of holiday cheer at 15 bars in downtown Green Bay. Here’s how it works: Buy a $15 playing card at one of the bars, or online for $20, get stamps from each establishment you visit during the crawl and then redeem your stamps for raffle tickets at Keggers for a chance to win something from Santa’s prize sack, including $500 cash and nine prizes of $100 cash each.

A few rules from the big guy: Must be 21 and older. Limited to the first 700 participants. Drink purchase not required. Noon-9 p.m. Saturday; $15 tickets (limited number) in advance at participating bars or $20 at bars and lyricroomgreenbay.ticketfly.com. Playing card pickup begins at 11 a.m. at Keggers, but participants can start the crawl at any time from noon-9 p.m.; cards must be returned to Keggers by 9 p.m.; winners announced on Facebook on Sunday.

'A Christmas Carol, The Musical'

Charles Dickens’ classic story gets a musical telling with Birder Players’ seven-performance run. A large cast performs the story of Scrooge, a man whose life must change — or else. “We all know, there’s a little bit of Scrooge in each of us. Despite our good intentions, we race through our busy year, often losing sight of the important things in life — time with our loved ones, gratitude for our many gifts, and charity to help those in need,” says director Alicia Birder. 7 p.m. Dec. 13-14, 2 and 7 p.m. Dec. 15; Broadway Theatre, 123 S. Broadway, De Pere; $26; birderstudio.org.

'A Charlie Brown Christmas Live on Stage'

“I bring you tidings of great joy, which shall be to all people ...” If it doesn’t feel like holidays until you hear Linus deliver his speech on the true meaning of Christmas in the classic 1965 Peanuts TV special, you can double dip this year. Charlie Brown, Snoopy, Lucy, Linus and the rest of gang bring the timeless story to life at the Weidner Center, complete with the music of Vince Guaraldi and a concert of Christmas carols performed by the characters. 7 p.m. Dec. 21; Weidner Center, UW-Green Bay; $41-$23; ticketstaronline.com, (800) 895-0071.

Santa Cycle

Mr. Claus is partial to traveling by sleigh, but there’s nothing in the Christmas playbook that says biking in December can’t be a jolly good time, too. Bike enthusiasts are invited to put on their Santa suit or or most festive holiday garb and bike a 7-mile course in Green Bay to benefit Children’s Hospital of Wisconsin. 10 a.m. Saturday; ride begins and ends at Badger State Brewing Co., 990 Tony Canadeo Run, Ashwaubenon; $35 adults, $15 ages 20 and younger; facebook.com/SantaCycleGreenBay.

Holiday Pops

The 150-voice Dudley Birder Chorale is the star of the annual Holiday Pops concert, but the group made up of singers from more than 30 communities will also get an assist from some guest elves. Under the direction of Kent Paulsen, the chorale will join the Holiday Pops Orchestra and 90 voices from the Birder Studio of Performing Arts to perform classic carols and festive songs. The Northeastern Wisconsin Dance Organization will perform a ballet sequence to “The Skater’s Waltz.” 7:30 p.m. Friday and 2:30 p.m. Saturday; Weidner Center; $58-$14 adults, with discounts for children and seniors; ticketstaronline.com and (800) 895-0071.

Allouez Village Band Christmas Concert

The band moves from its regular home at the Meyer Theatre to the Weidner Center, where there’s double the seating for a family-friendly concert with the theme of “Once Upon a Time ... Visions of Sugar Plums Danced in My Head.” The 75-member group, under the direction of Michael Ajango, will be joined by vocalists Amanda Abegglen and Tim Olejniczak for holiday favorites. It’s only the fourth time in the last decade the band has played the Weidner. Attendees are asked to bring nonperishable canned and dry good donations for the band’s annual collection for Paul’s Pantry. Doors at 6 p.m., concert at 7 p.m. Dec. 17; Weidner Center; free; allouezband.org.

Festival of Trees

It’s not just anywhere you can see more than 40 decorated Christmas trees, much less under the same roof as the the world’s largest steam locomotive. Local businesses and nonprofit organizations show off their creativity by decorating a tree. It’s also a chance to enjoy the museum’s train exhibits. Regular admission of $10 adults is reduced to $5 during Festival of Trees. 9 a.m.-5 p.m. Monday-Saturday and 11 a.m.-5 p.m. Sunday through Jan. 6; National Railroad Museum, 2285 S. Broadway, Ashwaubenon; closed Dec. 24-25 and Jan. 1; closes at 2 p.m. Dec. 31; $5; nationalrrmuseum.org.
